Florida and car seats

[Blakes87]

Hi
Booked to go to Florida in easter hols and not sure what to do about kids car seats. We have hired a car for the two weeks and my boys are 8yrs and 6yrs. Best to hire car seats out there or take our own? Would I need to take high back booster or just booster? Any advice welcomed
Thanks

I'm taking dds boostapack. It adjusts the seartbelt appropriately and is FAA approved.

Why do the seats need to be approved by the FAA? Isn't that concerning air safety?

I misread the ops ages I thought it was 3 and 6 ..... if you use one on the plane it needs to be FAA approved just for the car, car seat is whatever.

We took a bubble bum for DD
